Upstream moved under 145 profiles: 679 refs shifted and 452 followed a renamed file, against 6,483 that still anchor where they were written. The recale rewrites the located ranges only, keeping the annotations and the sentences that carry them, and 106 pins advance in the same commit because refs and source_commit name one revision or the profile describes two at once. Nothing here was guessed. The 183 refs that are CHANGED, GONE or AMBIGUOUS are untouched, and the 57 profiles holding them keep their old pin until someone reads the diff: profile_sync refuses to recale a profile while any of its refs needs a re-read. trident kept its pin too, its annotated ref being one the writer will not rewrite.

|
|
Vircon32 is a libretro core for the Vircon32 fantasy console, a 32-bit
|
|
virtual game console with fixed hardware specs (60 fps, 640x360, 16
|
|
sound channels, up to 4 gamepads).
|
|
|
|
The Standard BIOS v1.2 is embedded directly into the core binary as a
|
|
C header (embedded/StandardBios.h), generated from Assets/StandardBios.v32
|
|
at build time. The core never strictly requires an external BIOS file.
|
|
|
|
BIOS loading logic (libretro.cpp:415-429):
|
|
1. Check if system_dir/Vircon32Bios.v32 exists on disk
|
|
2. If found, load it via Console.LoadBiosFile() (external override)
|
|
3. If not found, load the embedded BIOS via LoadEmbeddedBios()
|
|
|
|
This runs inside context_reset() (libretro.cpp:473-474), which is called
|
|
whenever the OpenGL context is (re)created.
|
|
|
|
The BIOS file format is a V32 ROM with a specific signature
|
|
(ROMFileFormat::BiosSignature). It must contain exactly 1 texture and
|
|
1 sound. The loader validates the signature, file structure, and version
|
|
compatibility before loading program ROM, video ROM and audio ROM
|
|
(ConsoleLogic/V32Console.cpp:259-431).
|
|
|
|
The external BIOS file allows users to replace the boot animation with
|
|
a custom one. Game compatibility is not affected by BIOS choice.

Optional external BIOS placed in the system directory root.

The hashes above correspond to the Standard BIOS v1.2 bundled
|
|
in Assets/StandardBios.v32 of the source repo. Custom BIOSes
|
|
will have different hashes but must follow the V32 BIOS format.

|
|
note: |
|
|
The standard BIOS is compiled into the core binary as
|
|
embedded_StandardBios[] via a generated header file. It provides
|
|
the boot animation (Vircon32 logo + startup sound). LoadEmbeddedBios()
|
|
writes the raw bytes into a stringstream and passes it to
|
|
Console.LoadBiosData().

|
|
note: |
|
|
A V32 BIOS ROM file must have:
|
|
- BiosSignature in the header (distinct from CartridgeSignature)
|
|
- Exactly 1 texture (boot screen graphics)
|
|
- Exactly 1 sound (boot sound)
|
|
- Program ROM, Video ROM and Audio ROM in sequential layout
|
|
The loader validates all of this before accepting the file.

|
|
note: |
|
|
Cartridges use CartridgeSignature with up to 256 textures and
|
|
1024 sounds. Program ROM can be up to 128M words (512 MB).
